Performing online damage evaluation of blades subjected to complex cyclic loads based on the operating state of a gas turbine enables real-time reflection of a blade?s damage condition. This, in turn, facilitates the achievement of predictive maintenance...

Fibre ropes offer beneficial properties for mooring of floating offshore wind turbines (FOWTs). However, the mooring line?s stiffness is both load-history and load-rate dependent. A quasi-static stiffness is observed for slow loading, with a higher stiff...

This work studies the Voce?Chaboche (V?C) material model parameter optimization for high-strength steel welded joints subjected to cyclic loading. The model parameters of each material zone in a S690 steel butt-welded joint were determined using an optim...
